2 The powerfu duoboc burner: oduar design for ratings up to 2 W arae operation Air preheater Combustion air fan in. 5 mm sheet stee ax. 50 cm between stabiisers Fabric compensators are essentia Air defector Burner Combustion air ducting Combustion air temperatures up to 250 C Weishaupt WK-series burners have been designed especiay for industria use. The moduar design of the burners, couped with their arge capacity range, makes them ideay suited to a broad spectrum of specia appications. oduar principe Weishaupt WK-series industria burners are of moduar design. That means the fan, pump station, and preheater station are a seected independenty of the burner. This concept offers a high degree of fexibiity in matching to the most diverse appications. Digita combustion management Digita combustion management ensures the simpe and safe operation of combustion pant. Emissions are minimised and economy is maximised. Insuated burner housing The burner housing is fitted with interna insuation (optiona extra on the ambientair versions of the WK 40 and 50). This significanty reduces the surface temperature of the housing during operation with preheated combustion air. The insuation aso provides effective noise reduction. Heat recovery using preheated combustion air any industria processes create high fue gas temperatures due to the high temperature of the medium used. 2 A heat exchanger in the fue can be used to recaim a arge amount of energy from these hot fue gases, increasing efficiency by up to 10 %. Weishaupt WK-series industria burners can be operated with preheated combustion air temperatures of up to 250 C. Nozze head shutoff device At burner shutdown, or when changing over to gas operation, a safety shutoff device ocated in the oi atomising system shuts off the oi fow directy in the nozze orifice, preventing the escape of any oi. oduating operation Within its operating range, the burner s output is matched to the current heat demand. Reduced capacity at start Gas-firing burners start at a reduced ignition oad capacity. In addition to this, WK(G)S burners rated over 17.5 W are aso equipped with an ignition burner. This means that initiay ony a sma quantity of gas fows into the combustion chamber. After the ignition phase the burner then drives to partia oad. Controed shutdown from partia oad Controed shutdown of the burner aways takes pace from the partia-oad position, thus preventing impact on the gas main.

4 Digita combustion management: recise, simpe, and reiabe Setting via the ABE contro and dispay unit Digita combustion management means optima combustion figures, continuousy reproducibe setpoints, and ease of use. Weishaupt WK-series burners are equipped as standard with eectronic compound reguation and digita combustion management. odern combustion technoogies demand a precise and continuay reproducibe dosing of fue and combustion air. Simpe operation Setting and contro of the burner is achieved using a contro and dispay unit. This is inked to the combustion manager via a bus system, enabing the user-friendy setting of the burner. The contro and dispay unit has a cear text dispay with a choice of anguages. An Engish/Chinese dua-screen version is avaiabe as an option shoud a Chinesecharacter dispay be desired. Fexibe communication options The integrated interface enabes a necessary data and functions to be reayed to a master contro system via, for exampe, ebus, odbus RTU, odbus TC/I, or rofibus-d. easures for saving energy and increasing safety and reiabiity Eectronic compound reguation with the W-F 100 and 200 combustion managers faciitates the extremey precise, hysteresis-free setting of the burner. This reduces fue gas osses and saves fue. Variabe speed drive reduces eectrica consumption and faciitates a soft start of the combustion air fan. The use of VSD aso reduces noise emissions by a considerabe amount. O 2 trim saves fue through a continua and extremey efficient optimisation of the combustion air. Different O 2 probes are avaiabe, providing suitabe soutions for amost a fues.

8 Emissions reduced by the mutifam principe Weishaupt s mutifam technoogy was designed for gas and dua-fue burners. By using a patented LN mixing head, NO x emissions on WKseries burners can be reduced to extremey ow eves. Weishaupt has set an a-new benchmark, achieving eves beow 80 mg/m on gas and 120 mg/m on oi, subject to the combustion chamber geometry. Weishaupt s mutifam burners meet the word s toughest standards. In those countries with particuary stringent environmenta egisation, such as Switzerand, mutifam industria burners are market sector eaders. Typica oi fame formation At the heart of Weishaupt s mutifam technoogy is a specia mixing assemby design, which distributes the fue among primary and secondary nozzes. This resuts in extremey efficient combustion thanks to recircuation of the fue gases directy at the mixing assemby. mg/m mg/m TA Luft (Germany) 1. BImschV (Germany) 10 to 20 W TA Luft (Germany) 1.

9 Fame monitoring for demanding safety requirements Testing and optimisation using a software too Weishaupt Fame Contro (W-FC) is a reiabe fame monitoring system designed to meet demanding safety requirements. W-FC 4.0 is for pant with mutipe burners firing from the same direction into a singe combustion chamber. The W-FC assemby utiises fame frequency to monitor each fame separatey via a oad-independent on and off threshod for each fue. The CFC... fame sensor functions in series with the QRA7 fame sensor on the W-F 100 or W-F 200 combustion manager. Note: If a turndown in excess of 4:1 or singe-burner operation is required, the higher specification W-FC 5.0 must be seected. W-FC 5.0 is for pant with mutipe burners firing from different directions into a singe combustion chamber, and for process pant with various fame sources. The W-FC assemby monitors each fame separatey via a oaddependent switching threshod for each fue. This guarantees a distinct differentiation from extraneous sources. The CFC... fame sensor functions in parae with the QRA7 fame sensor on the W-F 200 combustion manager. This convenient, oad-dependent setting of the on and off threshods rests upon the eectronic VLoad modue, which can be configured using software. W-FC 6.0 is to monitor fame stabiity on pant with fue gas recircuation for extreme NO x requirements. With this version, the QRA7 fame sensor monitors the fame whie the CFC... contros the fue gas voume, based on the stabiity of the fame, to ensure safe operating conditions. In this way, reiabe operation with optima emissions is achieved under varying conditions. The VLoad modue enabes a oad-dependent switching threshod to be taiored to the operating conditions. A versions meet EN 298 continuousoperation requirements. W-FC 4.0 For cassica parae firing into a combustion chamber, with a maximum turndown of 4:1 W-FC 5.0 For firing into a combustion chamber from opposing directions, and individua/staged firing of mutipe burners W-FC 5.0 For pant with various fame sources, such as waste and biomass incineration, process pant, etc. W-FC 6.0 CFC... fame sensor Fame root Combustion zone CFC..

Light-oi ignition burner Oi nozze A reiabe soution for the ignition of high-viscosity iquid fues when gas is not avaiabe or not permitted. Ignition eectrodes are used to ignite the oi injected by the piot burner. The piot burner is then used to ignite the main fame upon fue reease.

11 Variants D to F Optima ignition for high-viscosity iquid fues on WK(G)S80, using a high-quaity ignition burner This variant faciitates reiabe ignition at a consideraby reduced rating. An ignition eectrode is used to ignite the piot burner s gas mixture. The piot burner is then used to ignite the main fame upon fue reease. A typica LG botte (11/ kg) is adequate for ensuring reiabe ignition. For exampe, an 11 kg LG botte is sufficient for we over 00 ignitions. Fame monitoring is via a separate ionisation probe, which necessitates the use of a W-F 200 combustion manager. This reiabe soution was deveoped especiay for heavy and specia fue ois with widey varying characteristics. It is aso suitabe for extreme ignitions, such as cod-starting pant that utiises pre-heated combustion air.

Vertica execution 18 Reiabe operation: Safety-critica components such as the gas butterfy vave and its actuator, gas vave assemby, and gas pressure switches, are securey ocated away from hightemperature zones to ensure their reiabe operation. The offset position of the ignition gas vave protects it from high eves of radiant heat from the heat exchanger. h 6 1 h 4 16 Optiona h 5 h 6 17 Optiona Extended option (with accessory components) 20 28
